摘要： The invention relates to a hydraulic actuator with movement decoupling, that can be applied to actuations where a linear movement must be performed while ensuring the freedom of a rotary movement. A hydraulic cylinder (03) held on the fixed part of the machine comprises a piston (01) that can perform the required linear movement, said piston comprising a mechanical interface (11) that can transmit the linear movement towards the rotating part (08) by means of an axle or a concentric master tube (07) axially sliding in the rotating part and rotating therewith. The interface performs a decoupling between the linear movement and the rotating movement, leaving the rotating movement entirely free. The invention also relates to the combination of the main hydraulic actuator with a hydropneumatic converter, the converter comprising a pneumatic cylinder (24) containing an annular pneumatic piston (20). The pneumatic piston can drive at least one pressure amplifying hydaulic cylinder (19, 25) along with its linear movement.

摘要： The invention relates to a hydropneumatic actuator that can be applied to actuations where a linear movement must be performed while ensuring the freedom of a rotary movement. A main hydraulic cylinder (7, 10), used to generate an axial movement and driven by the rotating movement imposed by the machine on which the actuator is mounted, is controlled by a pressure amplifying hydropneumatic converter. Said converter is arranged around said main hydraulic cylinder and rotates therewith, and comprises an annular pneumatic piston (3) controlled by an outer fixed pneumatic directional vane (16) supplying the converter via a fixed distributor (12) comprising rotary joints forming the pneumatic interface between the distributor and the rotating part. The pneumatic piston integrates at least two pressure amplifying hydraulic cylinders (1, 5).

摘要： The invention relates to a regenerative pneumohydraulic pump for reducing the volume of oil in the system compared with hydraulic systems commonly used. The pump is actuated by compressed air which controls and supplies at the same time a hydraulic pressure generator (06), this generator consisting of a pneumatic cylinder provided with a piston having a through-rod constituting a double-acting hydraulic pump which is put automatically into reciprocating movement by the switching of a pneumatic directional valve (07) which is self-controlled by the variations in pressure in the pneumatic chambers (06C, 06D) of the generator (06). The pressurized oil obtained is conveyed towards a hydraulic ram (01) which actuates a payload. The return line of this ram (01) also has an adjustable flow-rate regulating valve (11) for moderating and regulating the speed of movement of the rod of the ram (01) when said rod is driven by the payload, so as to avoid the phenomenon of cavitation in the hydraulic circuit. The generator (06), by way of its regenerative principle, ensures the immediate recirculation of the oil from one hydraulic chamber (06A, 06B) to the other, thereby making it possible to reduce the volume of the oil reservoir (04) to the absolute minimum necessary. On account of its reduced space requirement, the pump can be used advantageously for all sorts of applications in vehicles.

摘要： A hydropneumatic actuator applicable to linear actuations, comprising arrangements the purpose of which is to create internally and regeneratively a hydraulic pressure from the movement of the movable parts. These arrangements make it possible to slow the movement by finely adjusting its speed when this is required for the usage. The actuator comprises an annular pneumatic piston (Pp) provided with a movable tube (21) crimped in the internal bore of the piston, the pneumatic piston (Pp) being able to be moved in an external cylinder (Cy) under the effect of a pressure differential applied to the exterior by pneumatic connections (X1, X2). The actuator is further provided with a coaxial hydraulic piston (Ph) provided with a rod (10) sliding in a fixed coaxial lining (19, 20) separating the two pistons which remain attached to each other by a mechanical connection (1 1) between the end of the rod (10) of the hydraulic piston and the end of the movable tube (21). The actuator further includes electrical or pneumatic control valves, adjustable chokes, non-return valves, and an oil reservoir (15) kept under pressure by a spring (16) adjustable by a screw (1). The reservoir can be connected through valves, adjustable chokes and non-return valves to both sides of the hydraulic piston (Ph).
